History

Founded in the 2nd century B.C. during the Roman occupation. Its original name has been the subject of some debate, Castra Postuniana, Soricaria or Castra Juli, the latter in honour of Julius Caesar, being the three possibilities proposed.

The Moslems saw the village's merits and fortified it heavily, appreciating both its strategic position and its fertile terrain. In 1240, it was reconquered by the Christians under Ferdinand III, who ceded it to the Council of Cordoba.

In 1565, it was sold to the Marquis of Priego, under whose control it remained until the middle of the 18th century.

In the 19th century, Castro del Rio was the scene of fierce fighting against the invading French..
